Overview
The LD6806F/12H,115 is a low-dropout regulator (LDO) from the NXP LD6806 series, featuring a fixed 1.2 V output voltage and a 200 mA current rating. It operates within an input voltage range of 2.3 V to 5.5 V and utilizes an SOT886 package. The device exhibits a typical dropout voltage of 60 mV at full load and maintains a low quiescent current of 1.0 µA in shutdown mode. It provides high power supply rejection ratio (PSRR) of 55 dB at 1 kHz and low output noise of 30 µV RMS. Integrated protections include thermal shutdown, current limiting, and ESD protection rated at 10 kV Human Body Model.
Feature Summary
- Ultra-low dropout voltage ensures high efficiency and minimal power loss under load conditions.
- Low noise performance with integrated ESD protection for reliable signal integrity.
- High-ohmic output state when disabled prevents leakage in multi-rail systems.
- Compact surface-mount packaging supports miniaturized mobile and portable designs.
Applications
- Mobile phone handsets requiring component miniaturization
- Cordless telephones needing stable low-voltage supplies
- Personal digital devices with analog and digital interface requirements
Procurement Notes
Verify the ordering suffix '115' corresponds to the specific tape-and-reel quantity or variant configuration defined by NXP Semiconductors. Confirm the SOT886 package availability and lead-free status. Ensure compatibility with the required 1.2 V output specification for the target application circuit design.
Selection Notes
Select this component for applications demanding a fixed 1.2 V rail with high current capability in a small footprint. The high-ohmic output feature distinguishes it from low-ohmic variants, making it suitable for bus-sharing scenarios. Evaluate thermal resistance requirements based on the SOT886 package's junction-to-ambient characteristics.
Part Context
The LD6806 series comprises ultra-low-dropout regulators designed for mobile appliances. The family includes WLCSP4, SOT886, and SOT753 packages with various output voltages ranging from 1.2 V to 3.6 V. The LD6806F/12H,115 specifically denotes the SOT886 package version with a 1.2 V fixed output and high-ohmic disable state.
Replacement Considerations
Direct substitutes within the same series include other LD6806F variants with different output voltages if voltage adjustment is permissible. Cross-package equivalents like LD6806CX4/12H offer identical electrical performance in a WLCSP4 package for space-constrained layouts.
FAQ
What is the output state of the LD6806F/12H when disabled?
The LD6806F/12H enters a high-ohmic (3-state) output state when the enable pin is deactivated, preventing current flow from the output.
Does the LD6806F/12H require external capacitors for stability?
Yes, the device requires an external load capacitance of at least 1.0 µF with an ESR between 5 mΩ and 500 mΩ to guarantee stable regulator behavior.
